- The great thing about usability testing…is that after running sessions with five participants…you'll have seen about 80% of the issues…that exist in your product.…You can run more people but the benefits,…the number of extra issues you find,…drops off quite quickly.…Also, even after five people it's likely…that you'll have seen enough severe issues…to keep you busy fixing things for a while.…It's better to run a small study,…make some changes, and then test again,…to confirm your changes have the right affect,…than it is to run one big study…and just get more confident that you found all the issues.…

Remember, you aren't looking for…any kind of statistical significance.…Instead, you're looking to identify and fix barriers…to people using your product.…If even just three of your study participants have an issue…with part of your UI, it's worth investigating solutions…because that indicates that many more people…will have that same issue in the real world.…It doesn't matter exactly how many people,…the issue is likely to be severe enough…

Run your own basic usability testing to find out just what your users need from your website, application, or device—and learn where to focus design improvements to have the biggest impact. Author Chris Nodder shows how to design a study so that it answers your questions, how to recruit the right participants, and how to set up the test environment. The course also teaches you how to moderate and observe a usability test, interact with participants and ask the right kind of questions, and then analyze the results and share them with your team in a meaningful way.
